title: New Measurements and Assignments in the Millimeter-Wave Spectrum of CD3OH
abstract: The ground state rotational spectrum of CD3OH has been revisited in the millimeter-wave range. A total of 216 transition frequencies have been measured and assigned in the 117-179 GHz spectral range, including about 40 transitions previously reported. The spectrum was recorded at the Justus-Liebig University in Giessen, Germany using a frequency modulated millimeter-wave spectrometer. The assignments for the CD3OH transitions were predicted based on energy levels calculated using preliminary results of the global fit of microwave, millimeter-wave, and far-infrared data of Walsh et al. (Paper FC04 presented at the 52nd International Symposium of Molecular Spectroscopy, Columbus, OH, 1997). The new measurements have substantially enlarged the accurate millimeter-wave component of the data set available for the global fit and have allowed Walsh et al. to obtain significant improvement in the CD3OH molecular parameters (J. Mol. Spectrosc. 188, 85-93, 1998). The low residuals between observed and calculated frequencies highlight the quality of the global fit results. Copyright 1998 Academic Press.
